you just said that you didn't enjoy writing about it, but what is your big takeaway. how do you view jefferson now? >> well, with some disillusionment because i always thought of him as a crusader for universal rights who was, unfortunately, stuck in slavery, but he wasn't stuck in it. he modernized it, he made it fit into a developing nation because he saw that slavery provided the fuel for the burgeoning american economy. slave labor provided $30 million in exports every year in the 1780s, and the country needed that money. when jefferson built monticello, he took out, unfortunately, a slave equity loan. he borrowed $2,000 against 150 slaves from a dutch bank. he was a pioneer in finding ways to turn slavery into cash. it's not a very happy story, but it's right there. >> all right. >> in the documents. >> henry, thank you very much.
